Most tools used for compliance and SBOM generation use SPDX identifiers
This change brings us a step closer to an easy SBOM generation.

currently, nuttx implements readv/writev on the top of read/write.
while it might work for the simplest cases, it's broken by design.
for example, it's impossible to make it work correctly for files
which need to preserve data boundaries without allocating a single
contiguous buffer. (udp socket, some character devices, etc)
this change is a start of the migration to a better design.
that is, implement read/write on the top of readv/writev.
to avoid a single huge change, following things will NOT be done in
this commit:
* fix actual bugs caused by the original readv-based-on-read design.
(cf. https://github.com/apache/nuttx/pull/12674)
* adapt filesystems/drivers to actually benefit from the new interface.
(except a few trivial examples)
* eventually retire the old interface.
* retire read/write syscalls. implement them in libc instead.
* pread/pwrite/preadv/pwritev (except the introduction of struct uio,
which is a preparation to back these variations with the new
interface.)
Some drivers may not implement certain ioctls, but applications
may still call these ioctl functions for consistency.
In this case, to avoid an assertion, return ENOTTY.

We need to configure the priority of FB Vsync thread to prevent nxcamera from preempting scheduling without sleep, which currently causes issues with Goldfish x86_64's default FIFO scheduling.

Some devices need to clear the fb panbuf when waking up from sleep
to avoid outputting residual buffers from before sleeping

when the vsync comes, fb drivers should call fb_vsync_pollnotify to notify POLLPRI, so that users can catch the synchronization time of vsync and do something.

In order to better use the Android goldfish emulator,
a GPU FB driver has been added. This allows the goldfish
emulator side to achieve more flexible display effects,
such as UI skins.

Fix default_value of ioctl(VIDIOC_QUERYCTRL)(id=V4L2_CID_3A_STATUS)
to AE operating and AWB operating, because both AE and AWB are
automatical adjustment mode by default.
Because the exposure time and ISO sensitivity are adjusted automatically
by default, the default value can not be defined.
So, return the value out of range as the default_value of
ioctl(VIDIOC_QUERYCTRL).
which is useful in the m2m usage scenario, by replacing the first
argument of callback from "struct v4l2_ops_s *" to "struct file *"

Adjust the v4l2 framework to support both capture and v4l2m2m,
and can easily add other v4l2 features.
